Pantakarn is a very good host, with warm hospitality and willingness for help! His condo is located in a very good area, a busy junction between Ekamai and Tonglo, and Donki at the opposite. Therefore, noiseness is the only problem of his condo, and sound proof of windows needed to be reinforced. Double glass is suggested. I found that a huge gap is still existed at a closed window in the guest bedroom.
Nevertheless, a good memory in the past month. Thanks a lot!
